Mike,
Off the 16-yard line, I run Briley Mod tubes and an Improved Modified tubes off the 27-yard line using 34" barrels. Keep in mind that my trap guns are set up to shoot 14" high and I break clays right out of the house. If your letting them get out, you may have to choke a little tighter.
On my double guns, I run a loose modified and modified tubes out of 30" barrels. My break point of the second clay would be were you would be at the 23 yard line, again the first clay is right out of the house.
Also, forget about trying to shoot hot goose loads, my practice loads are 1-1/16 @1200 to allow me to shoot longer during practice. I only step up to 1-1/8 AA loads during match shoots. Plus, a hotter load stands a good chance of blowing the shit out of your pattern, or just opening it up way to fast.
Flash-hider,
The one thing that you are forgetting is those trap match shooters are money shooters. During a match shoot, it's not uncommon to have hundreds of dollars on the line is side bets, then if you include price money, you get the idea why there is so much tension during practice. In the heat of season, trap shooting is a 9 to 5 second job, so please keep that in mind.
Bottom line is when it comes to practice, most of the time I shoot with the same practice squad, or on a different trap house that is not set up for occasional shooters (set short and slow). Trust me, I’m not one of the people that you see bitching, rather I’m the guy that you see shooting off on a different trap house or sitting very quietly on the bench, looking out into space going over break point and the rhythm of the throws that each machine is putting out (it helps if you are shooting leagues during the week).
As for skeet shooting, again I am keeping my head in my own shooting, and often just stay quiet watching the throws/timing when others are in the box. If someone is shooting 3-4-5 behind the target, I will offer input on distance to increase (never in a match), but for the most part during practice, my mind is on my own shooting. If I am going to help someone out, I will not shoot that round and give them advice on style and break points, but have found that during my own time to practice, I need to stay focused on my own shooting and break points (much faster out of the houses, and very different break points than beginning shooter that often take the clays for a walk across the in bounds).
So as you see, most of us are not snobs, just in our own little world going over our game plan/own style.
